Volumetric and 3D tortuosity, curvature and asymmetry measurements were assessed for the first time from magnetic resonance (MR) data against ultrasound (US)-derived diameters, in a pilot cohort of 26 patients with abdominal aortic aneurysm (AAA) disease. We demonstrated that MR multidimensional analysis can better detect morphologic aneurysmal differences over time compared to diameters extracted from US imaging, which is the current clinical standard method for assessing AAA progression. Our 3D descriptors correlated more strongly with MR volumes, compared to US diameters at baseline and over time. Following further assessments in a larger patient cohort, this multidimensional analysis may enhance rupture risk prediction and improve clinical decision making.
